The fault information generally indicates a fault code returned by the fault, and then the fault type can be determined according to the fault code, for example, it is determined that the leakage fault occurs. Each breaker corresponds to an installation place, so that the fault place can be determined according to the breaker identification which sends the fault code. For example, assuming that each household is equipped with a circuit breaker, the fault can be directly localized to a specific residential household. Because the fault often leads to the power failure of the whole floor or the whole building, if the fault can be quickly positioned to which fault occurs, the maintenance speed can be greatly improved, and the influence on other users is reduced as much as possible.

Meanwhile, the severity of the fire can be analyzed through field images shot by the fire-fighting camera, different countermeasures can be adopted according to different severity, and therefore panic and loss caused by the fire can be reduced to the maximum extent.
Aiming at the condition that the circuit breaker is directly installed at each household, the resident users with faults can be directly positioned. However, for some residential buildings, only one breaker may be installed in the whole building, and the location of which building has a fault can only be determined according to the breaker identification. For this situation, it is necessary to further locate which user has a circuit fault.

Aiming at fault location of the whole building, the circuit breaker is respectively connected with a main circuit of each household and a power transmission line of each household, an indoor master control switch is installed on the main circuit of each household, and a line master control switch is installed on the power transmission line of each household. The power distribution cabinet is provided with the line self-checking module, and when a power utilization fault occurs in a certain building, the line self-checking button is pressed, and then a user where the fault is located can be automatically located. Specifically, whether the power transmission line or the main circuit has a fault is determined, the indoor main control switch of each user is controlled to be turned off through the line self-checking module, at the moment, current only passes through the external power transmission line, electricity utilization information is collected through the sensor module in the circuit breaker, the collected electricity utilization information is transmitted to the server, the server judges whether the power transmission line has the fault according to the electricity utilization information, and if the power transmission line does not have the fault, the fault is shown in the main circuit.

Besides being capable of timely positioning faults when faults occur, the server can also perform early warning on the faults which possibly occur according to the power utilization information sent by the breaker, and the faults are prevented in the future. By analyzing the electricity consumption information within a preset time period (for example, within one week) before the fault occurs, the rule before the fault occurs is found out, for example, a steep increase of the electricity consumption or fluctuation of the voltage or the current may occur before the fault occurs. After the rule is found out, the current acquired electricity utilization information of the current breaker in the preset time period can be analyzed, whether the fault risk exists or not is judged, and if the fault risk exists, early warning information is sent to the corresponding user terminal. In one embodiment, a model learning mode can be adopted to obtain the rule of the electricity utilization information before the fault occurs. For example, the power consumption information in a preset time period before the fault occurs may be compared with the previous power consumption information in a model learning manner, so as to automatically learn the rule before the fault occurs through the model. For example, assume that the power consumption of the day before the occurrence of a fault is taken as training data and labeled as fault risk (which may be replaced by 1), while the power consumption of each day before the year is taken as training data, and then each piece of training data is labeled as risk-free (replaced by 0). After the training data is constructed, the model can be used for training, for example, a linear model can be used for training, and the relevant rules can be automatically learned through the linear model. By finding out the rule before the fault occurs, risk early warning can be carried out in advance, and precaution can be achieved in the bud.
